WIRE-STRETCHER.

SPI-' CiFECATlN forming part of Letters Patent No. 313,165, dated March 3 1885.

Application filed April 21, 18S-4. (No model.)

To @ZZ whom 15 mfty/ concern:

Be it known that I, JOHN E. BLAOKMORE, of Walnut, in the county of Pottawattamie and State of Iowa, have invented an Improved FeneeNVire Stretcher, of which the following is a specification.

My invention relates to that class of devices that are designed to be fastenedy to a fixed post to draw a fence-wire along a line of posts, and to stretch and hold the wire until it is fastened to the post by means offencestaples; and my improvement consists in the construction and combination of a frame, a rotating and sliding shaft, adrum, a drumlocking device, a wire-holding device, and a chain having a spike on its end, as hereinafter fully set forth, in such a manner that the complete device can be readily fastened to posts of various sizes and at any elevation desired, and to extend at right angles to a line of posts, to facilitate stretching and fastening a number ofwires to the fixed posts to produce a wire fence.

Figure l of my accompanying drawings is a perspective view of my machine in position on a post as required for practical use. Fig. 2 is a top view ofthe frame and chain attached to a post. Fig. 3 is a view of my Wireholding device.

Jointly considered, these iigures clearly illustrate the construction, application, and operation of my complete invention.

A represents a nieta-l frame of oblong shape, that may vary in size as desired.

B B are shaft-bearings that project at right angles from the ends ot' theframe and are cast integral With the frame.

C is a curved extension at one end of the frame, and on the side opposite to the shaftbearings B.

D D are handles formed on or fixed to the ends of the frame.

F is a straight shaft adapted to slide through perforations in the parts B of the frame.

G is the barrel of a drum, adapted to receive the sliding shaft in such a manner that it can be adjusted on and fastened tothe shaft by means of a spline or set-screw.

H is a flange or Wheel formed integral With the end of the barrel G. It has semicircular notches in its periphery.

-J is a bar pivoted to the frame in such a manner that it will move at rightY angles to the notched flange H of the drum, and in a plane parallel with the frame A, as required to be pressed in and out of a notch in the said flange. To lock the drum after it has been rotated to draw a Wire to the post, l simply press the barJ upward to engage one of the notches, so that the flange and drum will be jointly latched to the frame, and the force of the wire applied to press the bar J against the frame until the Wire is fastened to the post. After the Wire is fixed to the post the hold of the clamping device upon the wire can be released and the pressure of the flange upon the locking-bar 'relaxed and the bar disengaged from the flange and drum.

To lock the bar or latch J to the frame, a pin may be passed through a perforation in its free end into a coinciding perforation in the frame.

- M represents my Wire-holding device, connected with the drum G by means of a rope or chain. It is composed of two short flat bars, N, that have open slots P, and that are pivoted together in such a manner that a fence- Wire can be pressed into one of the slots, and the other bar then pressed into parallel position with its mate, to aid in clamping and retaining the Wire as required to draw and stretch it. By attaching the wire to the drum. it can be drawn and fastened to the same post that supports the drum.

From the foregoing detailed description of each part of my machine its practical operation' and advantages will be obvious to persons familiar with the art of making wire fences.

l claim as my invention- The improved Wire-stretcher composed of the frame A B C, having a chain, K, attached, and a pin or spike on the end of the chain, a rotating and sliding shaft, F, a drum having an annular flange and notches in the periphery of its flange, a pivoted "locking-bar, J, and a rope or chain having a Wire-clamping device on its end, substantially as shown and described, to operate in thef manner set forth.

JOHN E. BLACKMORE.
